[ all whom, it iii/my concern.-

Be it known that I, EDMUND SCHULZE, a citizen of the United States,residing at Lyons, in the county of Burt and State of Nebraska, haveinvented certain new and useful Improvements in Hay-Stackers, of which.the following is a specification.

This invention relates to hay stackers of that class which are equippedwith a movable platform, sometimes known as the stacker-fork, and whichare used in connec-- tion with drag rakes whereby the load that is to beelevated and deposited upon the stack is conveyed to the stacker andplaced upon the stacker-fork while the latter is loweied to a receivingposition.

The object of the present invention is to furnish an appliance, known asa retaining device, adapted to be secured upon the teeth of thestacker-fork, for the purpose of retain-' ing the load upon the latterwhile the rake is being backed away from the latter.

A further object of the invention is to pro- Vide a retaining devicewhich, while it will efliciently fulfil the function of retaining theload upon the stacker-fork, will in no wise hinder or interfere with thedischarge of the load upon the latter.

Further objects of the invention are to simplify and improve theconstruction and operation of this class of devices, and to provide anattachment which may be readily, and at small expense, applied tostackerforks of ordinary construction.

With these and other ends in view, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement of parts which will behereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention may be resorted to when desired.

In the drawingsFigure 1 is a perspective struction, equipped with tneimproved retaining devices. Fig. 2 is a longitudinal sectional viewtaken through one of the teeth of the stacker-fork. Fig. 3 is asectional elevation showing a stacker-fork in load receiving position,and showing also a drag rake which is being backed off after deliveringor depositing a load upon the fork. Fig. 4 is a side elevation, partlyin section, of the improved retaining device.

Corresponding parts in the several figures are denoted by likecharacters of reference.

A in the drawings designates a stacker head of ordinary construction,the same comprising the cross-bars 1, 1, teeth 2, 2, and upright guardbars 3, 3; the head is carried by the frame bars -i4, which are a partof the stacker mechanism.

The improved retaining device consists of an inclined rod or bar 5,preferably made of round iron, the same being provided at its front endwith a fiat base portion 6 having a countersink aperture 7 for thereception of a fastening member, such as a bolt or screw 8, whereby itmay be secured upon one of the teeth 2, near the forward extremity ofthe latter. The rod is inclined upwardly and rearwardly and it isprovided with a foot member 9 which is curved downwardly and forwardlybeneath the body of the rod 5, and which terminates in arearwardly-extending flattened base piece 10 having a countersunkaperture 11 for the passage of a fastening member 12. That portion ofthe body 5 which extends rearward of the foot piece 9 is curveddowardly, as shown at 13, and it terminates in a moderately sharp point14.

It is preferred to provide the teeth of the stacker head with recesses,as shown at 15 in Fig. 2, for the reception of the flattened baseportions 6 and 10 of the retaining attachment, in order that the uppersurface of the teeth may be left smooth,thus avoiding liability of themovement of the hay onto or off the stacker head being obstructed.

The improved retaining attachment may be constructed at small expense,by casting of malleable iron or other suitable material; or it may beconstructed, by forging, of wrought iron or steel in an efficient andmaxpensive manner.

In practice it is preferred to mount one of the improved retainingdevices upon each tooth of the stacker head, as will be seen in Fig. 1of the drawings; but this is not essential, and one or more of the teethmay, if desired, be left free from the retaining devices. I

The operation and advantages of the invention will be readily understoodfrom the TCO IIC

foregoing descriptioi'i taken in eonnectio'i'i with the accompanyingdrawings. When the stacker head is in. the load-rcccivil'ig position,indicated in Fig. 3 of the drawings, a load of hay may be depositedthcreol'i in the usual manner by a drag-rako of ordinary(,(,)11SlJIU.Utl(.)11 a rake of this character being conventioi'iallyshown at It in Fig. 3 of the drawings. When the rake is being withdrawn,the load Will be engaged by the retaining devices, the points 14- ofwhich. Wlll enter into and engage the load it the latter exhibits atendency to slide oil the stacker head; and said points being slightlydownturned will cause a portion of the load to pack in the spacesbeneath the rear ends of the body portions 5 and in rear of the footportions 9 of the retaining dev1ces, thus causing the load to becomehrmly gripped and held against further movement while the rake is beingbacked away from the stacker. When the stacker-fork is manipulated toele vatetlie load, it is tilted in the usual manner, and" the load willbe discharged over the guard members 3, as is Well understood; the

retaining. devices Will thus in no wise hinder or obstruct the dischargeof the load.

The improved retaining devices )fthe present invention are simple,inexpensive, and thoroughly efficient for the )urposes for which theyare provided; and t ey may be,

at a trifling UX'POHSO, applied to the heads o'l? stackers ol ordinaryeonstructim'i and in present use.

What is claii'ned is l. A retaining device for hay staekers consistingo'l" a rod su' morted upon a tooth ojl a stacker head in an n nvardlyand rearwardly inclined position and having a terminal downtnrned pointand a forwardly curved foot orsu 'ipm'ting member set forwardly beneaththe body of the retainii'lg member.

2. A load retaining device for hay staekers consisting of a rodsimported upon a teeth of a stacker head in an upwardly and rearwardlyinclined position and having a l'lat tened. apertured base member at itsfront end, said rod having a tern'linal downturned point at its rear endand a forwardly-curved foot set forwardly beneath the body of theretaining device and having a flattened apertured base plate.

3. A load retaining device "for hay staekers comprising a body and afoot member eon.

verging in a rearward extending terminal U point, and having aperturedbase plates.
